Historical Aerial Imagery on Google Maps

Neighborhood Change in Connecticut, from the University of Connecticut, uses the Google Maps API to allow users to compare historical aerial imagery with Google's more recent imagery.

Users can search for any Connecticut address and compare aerial imagery from two time periods, side by side. It is currently possible to select satellite imagery from 1934, 1990, 2004 and 2006. Aerial imagery from the 1950s and 1970s is also in the pipeline.

The opacity of the aerial photo layer can be
adjusted. This means it is possible to compare the aerial view of the
state in the 1930's to Google's current satellite imagery and observe
how the state has developed over the last 80 years.
